Why does my ProCurve Switch 5308xl (J4819A), 5372xl (J4848B), 5348xl (J4849B), and 5304xl (J4850A) stop forwarding packets across modules after several weeks of continuous operation?
In software versions prior to E.06.03, there is a synchronization issue between the switch chassis and modules that can occur after several weeks of continuous operation. This can result in packets being dropped by the switch instead of being forwarded. This issue is fixed in software version E.06.03, or greater, available on our website at “Software updates” page. If you believe you are experiencing this issue, rebooting your 5300xl switch will temporarily resolve the situation until you upgrade to software version E.06.03 or greater.
